Hello, this is Ken Kuwako, your Science Trainer. Where every day is an experiment. “Sound” is invisible to the naked eye. But wouldn’t you feel a spark of excitement if you could capture those invisible waves perfectly using just math and experiments? Today, I’m introducing a lesson on “Air Column Resonance.” We’ll combine modern tablet […]

I’m Ken Kuwako, your science trainer. Every day is an experiment. 【This article is also available as a radio segment!】 Have you ever seen something magical—where “invisible” light suddenly appears as a sharp, vivid line right in front of you? You may have seen scenes in movies where a spy slips through a web of […]

Science Trainer Ken Kuwako here. Every day is an experiment. Have you ever experienced that ringing in your ears or that feeling of being squeezed when you dive deep into a pool? That’s the force of water pushing against an object—what we call “water pressure.” But since this force is invisible, it’s surprisingly hard to […]

Hello, I’m Ken Kuwako, your science trainer. Every day is an experiment. Ever wondered what the shape of invisible “sound” looks like? You might picture pricey gear in a science lab, but the truth is, you can pull off surprisingly professional experiments using simple, everyday items. Today, we’re diving into the “standing wave” (teijou-ha) experiment, […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment. Have you ever listened closely to the “Tock-tock-tock…” sound as you pour boiling water from a kettle into a thermos? That simple, everyday sound actually hides a scientific mystery about “sound” that you learn in middle school science. Today, I’ll be talking about the […]
